Hi Mike!
As described in the JSF book of Hans Bergsten, a member of the JSF specification team, the value attribute value of a h:dataTable can be of any type, but the primary model type is the javax.faces.model.DataModel class. - a value of type Object[] is wrapped automatically in an instance of ArrayDataModel - a java.util.List in a ListDataModel - a javax.servlet.jsp.jstl.sql.Result in a ResultDataModel - a java.sql.ResultSet in a ResultSetDataModel - and any other type in a ScalarDataModel If the HtmlNewspaperTable is based on the JSF standard HtmlDataTable (what can be seen in the API Doc), why is the value attribute value of type java.util.Set not supported? Or is the info of Hans Bergsten not correct?
